Description

    RELATED APPLICATION
  • This application claims priority under 35 U.S.C. §119(e) to commonly-owned, co-pending U.S. Provisional Patent Application Ser. No. 60/219,901 entitled, “Intermodal Container Pallet,” filed Jul. 21, 200, which is hereby incorporated by reference in it's entity.[0001]
  • BACKGROUND OF THE INVENTION
  • The present invention relates to pallets for intermodal shipping containers and, more specifically, to pallets that facilitate fork-lift hoisting of intermodal shipping containers. [0002]
  • DESCRIPTION OF THE RELATED ART
  • In the cargo container industry, the sizes of a container have been standardized by the International Organization for Standardization (ISO). There are standardized containers with lengths of 10, 20, 30, 40, 45, 48, and 53 feet. The containers have also been standardized to a width of 8 feet and a height of 8 to 8.5 feet. It is to be appreciated that these containers will herein be referred to as “intermodal containers.”[0003]
  • Most twenty-foot intermodal containers and all intermodal containers greater than twenty feet in length do not have slots at their base and are therefore lifted and moved by top corner castings with top lift trucks. However, using top lift trucks to move such intermodal containers can be cumbersome, such top lift trucks can be expensive and such top lift trucks typically result in the intermodal containers being stacked on top of one another. In addition, using top lift truck to move and store the intermodal containers can result in an inability to retrieve and store stacked intermodal containers efficiently in a container storage system, such as is disclosed in U.S. Pat. Nos. 5,062,242 and 5,140,787, herein incorporated by reference. Such a storage and retrieval system is best utilized if an intermodal container can be placed into the various rows and columns of the storage system from a side of the system. The top lift trucks do not allow an intermodal container to be loaded into the system from the side. [0004]
  • In addition, if an attempt is made to lift any intermodal container of twenty feet in length or greater at its base with a fork-lift truck, the intermodal container may collapse, or since the loading of an intermodal container is rarely evenly balanced, tipping of the intermodal container may result. [0005]
  • SUMMARY OF THE INVENTION
  • It is an object of this disclosure to provide an intermodal container pallet or an intermodal container that facilitates lifting and movement of such intermodal containers with a fork-lift truck, and, in particular, lifting of intermodal containers from a longitudinal side of the intermodal container without the intermodal container collapsing or without the intermodal container or fork lift tipping to one side.

  • DETAILED DESCRIPTION
  • The following description sets forth some embodiments of an intermodal container pallet and intermodal container of the invention. However, it is to be appreciated that various alterations, modifications and embodiments may be readily apparent to one of skill in the art and although not explicitly described, are herein contemplated by the disclosure. [0029]
  • It is to be understood that according to this disclosure an “intermodal container” is a standardized packing case for cargo in which goods can be safely stored and/or transported by road, rail, air, or sea. However, it is also to be appreciated that any container can be used with the intermodal container pallet of this disclosure. [0030]
  • Installation of a high density mobile storage and retrieval system, such as described in U.S. Pat. Nos. 5,062,242 and 5,140,787, can solve significant problems which now encumber container yard operations. For example, an inability to retrieve and store stacked intermodal containers efficiently is an underlying cause of the logjams in container yards. Using the above-mentioned High Density Mobile Storage and Retrieval System can provide methodical and efficient storage and retrieval of cargo, can eliminate traffic jams, can minimize demurrage charges, can use much less acreage than is now being used, and can do away with any need to acquire additional land, new railroad systems and cargo handling systems. [0031]
  • However, in order for these High Density Storage and Retrieval Systems to be installed and utilized in their preferred operation, intermodal containers are preferably stored and retrieved from a side of the intermodal container. Thus, there is a need for a device that will make it possible to store and retrieve intermodal containers from the side of the intermodal containers within the above-mentioned high density mobile storage and retrieval system, or within any storage and retrieval system for storage and retrieval of intermodal containers. [0032]
  • One solution to the aforementioned problems is to modify a base of existing intermodal containers by attaching an embodiment of an intermodal container pallet of the invention to the base of the intermodal container pallet. Another solution is to fabricate an ISO certified intermodal container with an embodiment of an intermodal container pallet integrated with the structure of the intermodal container. According to one embodiment of the invention, an intermodal container pallet can be attached to the base of an intermodal container, for example, by joining conventional corner castings or twist lock mechanisms of the intermodal container pallet to the corner castings of the intermodal container to secure the intermodal container pallet to the intermodal container. With this arrangement, a strength of the base of the intermodal container along the entire length of the intermodal container can be increased. In addition, with this arrangement, the intermodal container pallet can be equipped with fork channels that facilitate a fork-lift truck to lift the intermodal container from either longitudinal side of the intermodal container at the base. For example, according to one aspect of this embodiment the intermodal container pallet can be provided with four fork slots.

Fantuzzi fork-lift trucks are available from Fantuzzi Reggiane Via Cisa Ligure 51/A42040 Lentigione (RE) Italy.
  • FIG. 4 illustrates a bottom perspective view of an embodiment of an [0041] intermodal container pallet 10 of the present invention. According to one aspect of some embodiments of the intermodal container pallet of the invention, a bottom of the intermodal container pallet can be shaped and arranged so that it mates with a docking assembly 30, such as illustrated in FIG. 5. For example, referring to FIG. 4, the corner castings 22 may comprise an opening or gauge hole 26, located at the bottom of each of the four corner castings 22, that facilitate attachment to a corresponding twistlock mechanism located at each of the four corners of the docking assembly 30. The bottom of the intermodal container pallet can thus be shaped and arranged to have a similar shape and arrangement as a bottom of an ISO certified intermodal container as illustrated in FIG. 6. FIG. 6 illustrates a perspective view of an ISO certified intermodal container 40 and illustrates that the bottom of the intermodal container contains conventional corner castings 42. Thus, a bottom of the intermodal container pallet can be provided with conventional corner castings and shaped and arranged so that it substantially mates with a docking assembly for an ISO certified intermodal container, such as the docking assembly 30 of FIG. 5 that resides on a flat bed 34. The flat bed 34 of FIG. 5 is typically used to transport such intermodal containers. With this arrangement, the intermodal container pallet 10 can be substantially mated with the docking assembly 30 so that the ISO certified intermodal container can be attached to the intermodal container pallet and the combination can be transported by the flat bed 34.
  • It is to be appreciated that for some embodiments of the intermodal container pallet of the invention, the ISO certified intermodal container can also be transported by any of rail, air, or sea. In particular, a docking assembly can be provided on any of these vessels to transport an ISO certified intermodal container affixed to an intermodal container pallet. The docking assembly may comprise, but is not limited to, any platform that can mate with the four corner castings of the intermodal container pallet of the invention. For example, the docking assembly may comprise a cargo container storage and retrieval system such as disclosed in U.S. Pat. Nos. 5,860,783 and 6,077,019, herein incorporated by reference. It is also to be appreciated that the docking assembly may be provided on any vehicle that may be used in the transportation of the intermodal container and the intermodal container pallet by any of road, rail, air, or sea. For example, the docking assembly may be any surface having four corresponding twistlock mechanisms to mate with the four corner castings, as known to those of skill in the art. The docking assembly may also be the top of another intermodal container so that the intermodal container and intermodal container pallets can be stacked on top another to help maintain efficient use of space in a container yard or a vessel that ships the intermodal containers. [0042]
  • As has been discussed herein, some embodiments of the [0043] intermodal container pallet 10 of the invention can be attached to an ISO certified intermodal container by mating a conventional twist lock mechanism 32 at a top of each corner casting 22 to a corresponding gauge hole or opening located at the bottom of an ISO certified intermodal container. Such an ISO certified intermodal container can be, for example, one as illustrated in FIG. 1 of this disclosure. In addition, a fork-lift truck containing four prongs can insert the four prongs of the fork lift truck into the four fork slots 24 of the fork channels 12. This arrangement allows the fork-lift truck to raise and/or lower the ISO certified intermodal container and pallet, and to move the ISO certified intermodal container and pallet from one location to another location. An advantage of this arrangement is that the fork-lift truck provides more flexibility than utilizing top lift trucks. For example, the fork lift can be used to move the pallet and intermodal container and load the pallet and intermodal container in a storage system, such as disclosed in U.S. Pat. Nos. 5,062,242 and 5,140,787. Some embodiments of this storage system are preferably loaded from a side of the system and not from a top of the system with a top lift truck as is conventionally used in the industry. Thus, an advantage of some of the embodiments of the intermodal container pallet of the invention is that it facilitates an ability to lift an intermodal container along a longitudinal side with a fork-lift truck, to load or unload the intermodal container and pallet from a side of a storage system, and therefore eliminates any need for a top lift truck that can only load and unload the intermodal container from a top of the storage system.
